Dog Door

You are asked to create a dog door for a client. You are programming the remote that will do things such as open and close, etc.

• It should open (saying "The dog door is open.") and close (saying The dog door is closed.").
• It should take into account a dog going outside and coming back in; it should open when the dog barks, recognize the sound of the owner's dog and not other dogs, not let other dogs are animals in by closing when necessary (use Timer),
• Some people may want their dog door to lock/unlock all the windows in the house if a certain combination on a keypad is put in. Some people may want the door to detect the dog scratching the door.
• You should at least have Remote, BarkRecognizer, DogDoor, and Bark classes.
• You can use an Iterator to recognize barks.
• Make sure to use classes, objects, inheritance, polymorphism, etc.
